sPEcIFIoA'rIoN forming part of Letters Patent No. 413,743, dated october 29, 1889. Application tiled March 2,1889. Serial No. 301,752. (No model.)

To aZZ whom t may concern.-

Be it known that I, OHRIs'rIAAN TANGEN- BERG, a citizen'of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new 'and useful Improvement in Portable -Screening Flour- Bins, of which the following is a specification.

This invention relates to the construction of small-sized or portable iiour holders or re- Io ceptacles adapted to family use; and its ob ject is the production of a very cheap serviceable article, wherein the iiour may be securely kept and from which it may be withdrawn in varying quantities and screened as I5 it is thus withdrawn.V

My improvediiour-bin consists of a cylindrical vessel made of stiff paper, and is pro-l vided with the following adjunctiveA features, viz: a removable anged cover, a concave screen, and anl agitator immediately above such screen, anda removable drawer below and receiving the screened iour from such screen, such drawer being also provided with a removable close bottom and a screen-bot- 2 5 tom which can be used where a second screening is desired. These and other features of Iny invention are described, and shown in the accompanying drawings, in which latter- Figure l is an elevation, and Fig. 2 a central vertical section of my improved bin. Fig. 3 is a horizontal section. Fig. 4 is -a longitudinal vertical sectionv of the drawer for catching the screened ilour. Fig. 5 is an enlarged detail section of a portion of the Y 35 drawer, to show the-manner of supporting I l the close and screen bottoms, and Fig. 6 shows the agitator and its shaft. In said drawings, A represents a cylindrical vessel formed of paper and strengthened at both top and bottom by interior hoops a.

At the top is a removable hanged cover B,

Vand at the bottomV is a closeplate C, and preferably a surrounding iiange or hoop c, both the latter being permanently attached to the cylinder.

At D is a dished or concaved screen resting upon the edges ofthe downwardly-inclined close metal rim d. This rim d is supported upon the edge of aninterior hoop e. An-

l l 5o other hoop e may be placed below the hoop e,

`the primary purpose of which is to strengthen the cylinder just above the drawer-opening.

The agitator consists' of wire beaters or wings F, secured to a shaft F. The `shaft passes through openings d in the rim d, and is held against eudwise 'movement by the metal plate d2 at its inner end and the plate d3 at-its outer end, both said plates being secured ,to the hoop e. Wire loops f encircle the ends of the shaft, and being secured to 6o the hoop e by nails f support and hold the shaft vertical. As there may be some sagging or letting down by the screen, I form the wings F with bends f2, by the straightening out of which bends the diameter of the agitator may be slightly increased when such sagging has taken place, thereby keeping the proper relationship between the screen and the agitator.

For rotating the shaft a crank-handle G is 7o threaded into its outer end, and for purposes of strength, as well as to avoid the formation of an opening specially to receive the crank, theshaft is made of tubular metal, as indicated. The crank thus secured may be readily tallen out for purposes of shipment, &c. The crank also assists in supporting the Outer end of the shaft, and its diameter4 being less than that of the-shaft the latter cannot enter the opening in t-he wall-of the bin through 8o which the crank passes, so that no special provision to prevent end-thrust is requisite. The end wires F should pass through openings in the shaft and their ends be wrapped around the latter, as indicated.

The drawer is shown at H. It is provided witha removable close bottom h, and also with a screen-bottom h', so that by taking out the close bottom the flour may be again screened prior to using it. The close bottom 9o slides upon Vflanges t', formed by bending the metal wallforming the sides of the drawer, as shown at Fig. 5, and the screen is supported upon the metal angle-pieces j, soldered to the interior of the wall ofthe drawer.

I claiml. In a cylindrical pasteboard screening Hour-bin, an agitator mounted upon a shaft provided with supports located wholly within the bin and abutting at its ends against the Ioo inside Walls, in combination with a crank threaded into one end of the shaft and passing through an opening in the Wall of the bin of less diameter than the shaft, substantially as set forth.

2. 1n a cylindrical screening flour-bin made of pasteboard, the hoops e and e and the plates dzds, in combination with the agitator'- shaft, substantially as set forth.

3. In a cylindrical screening,r pasteboard our-bin, the agitator, the shaft whereof is supported from hoop e', and the dished screen supported from hoop e, in combination with said hoops, substantially as set forth.

4. The cylindrical screening flour-bin made of pasteboard, wherein are combined "an agi- `tatorand a screen D, said screen having a CHRISTIAAN TANGENBERG.
